  *
  * Used in:

  * The bignum code uses double-width division to speed up some operations.
  * Double-width division is often implemented in software that needs to
  * be linked with the program. The presence of a double-width integer
  * type is usually detected automatically through preprocessor macros,

  * and can be linked with an implementation of division for that type.
  * By default division is assumed to be usable if the type is present.
  * Uncomment this option to prevent the use of double-width division.
  *
  * Note that division for the native integer type is always required.
  * Furthermore, a 64-bit type is always required even on a 32-bit
  * platform, but it need not support multiplication or division. In some
  * cases it is also desirable to disable some double-width operations. For
